\note{If we look around us, we see software everywhere.\\[1em]
It powers our industries, fuels innovation, mediates access to all digital information,
and is a pillar of modern scientific research.\\[1em] %
%Our industry, our society, our own lives depend on software!\\[1em]
Software in general, and Free and Open Source software in particular, is at the heart of our society.\\[1em]
The Source code of this software embodies our collective knowledge, and is a growing part of our cultural heritage.\\
%Now the question is: are we taking care of it?

** Q: do you archive /only/ Free Software?
- We only crawl origins /meant/ to host source code (e.g., forges)
- Most (~90%) of what we /actually/ retrieve is textual content
#+BEAMER: \vfill
*** Our goal
Archive *the entire Free Software Commons*
#+BEAMER: \vfill
***
- Large parts of what we retrieve is /already/ Free Software, today
- Most of the rest /will become/ Free Software in the long term
- e.g., at copyright expiration
